A rod 29, disposed near the front of the machine, has its end portionsupturned and secured to the side bars 3. The rod 29 is b engagedintermediate of its ends by the strap 8 and 'is strengthened and bracedthereby. [Draft chains 30 are attached to the rod 29 near the outer endsthereof and intermediate said ends. Suspending chains 31 are alsoconnected to the rod 29 at corresponding points. Rear suspending chains32 are attached to the side bars 3 and coact with the draft chains 30 ina manner presently to be explained. V

Transversely alined cutting blades 33 are disposed in the rear of therod 29 and are supported by means of the suspending chains 31 and'32.The end portions of the cutting blades .33 are upturned, and the severalchains 30, 31 and 32 are attached thereto. he rear portion of each ofthe, cutting blades 33 inclines. upwardly and rearwardly frontportionlof each of the blades substantially in a horizontal tion of each0.

plane or slightly inclined. The rear porthe cutting blades 33 isdownturned, asindicated at 34c, and is aperturedat regular intervals, asindicated at 35, to receive the tines of rakes disposed in the rear ofthe cutting blades. Each of the cutting blades 33 is provided with abail 36 to which the lower end of an operating lever 16 is centrallyattached. .The pitch of the cutting blades 33 is varied by mov ing theoperating levers 16 in the slots of the arched bars 13, said leversbeing made secure in the adjusted position by means of the hand.latches15 cooperating with the teethlt in a manner well understood. Thedraft chains 30 extend substantiallyin a horizontal position and sustainthe stress incident to the operation of the cutting the cutting bladeswhen the implement is in active operation. The pitch or depth of actionof blades 33-may be regulated by adjusting the effective lengths of thesuspending chains 31 and 32.

The. rake, disposed in the rear of each of the cutting blades 33,comprises tines 37 and a connecting bar 38. The tines 37 may be securedto the bar 38 many manner and are attached to the respective cuttingblades 33 to admit of the rake asa whole having a shaking or vibratorymovement. The for-- Ward en s of the tines 37 pass through the openings35 formed in the downturned por tion 34 of the cutting blades. Theshaking rakes are held in position by bending the forward ends ofcertain tines to positwely engage the downturned edge portion 34.

crank portion 18 of the shaft 17 with the bar 38 of the respectiveshaking rakes. The lakes perform the office of separators wherey toremove roots, weeds and the like from the soil and deposit the same uponthe top thereof.

The implement operates chiefly as a pulverizer and leveler to prepareplowed land for the reception of seeds. thereby performing the dualofiice of clod crushing and earth pulverizing and leveling. As themachine is drawn over the plowed field, the cutting blades 33 passbeneath the soil and elevate the same thereby crushing and breaking upclods and leveling the soil. The earth passing over the rakes in therear of the cutting blades 33, is further loosened and leveled andweeds, root-s and the like contained therein are separated and depositedupon the top of the ground. The earth passes through the spaces formedbetween the tines 37 and the roots, weeds and the like are retained uponsaid tines and escape from the rear thereof, the separating action beingfacilitated by the shaking or vibratory movement imparted to the rakes,as will be readily understood.

What is claimed is:

1. In an implement of the character specified, a supporting frame, acutting blade, front and rear suspending chains for the cutting blade,and draft sustaining chains. 2. In an implement of the characterspecified, a supporting frame, a. cutting blade. front and rearsuspending chains for the cutting blade. and draft sustaining chains.said suspending chains being adapted to have their effective lengthsvaried whereby to regulate the pitch and the depth of action of thecutting blade.

3. In an implement of the character specified, a supporting frame, acutting blade, front and rear suspending chains for the cutting blade,draft sustaining chains, an operating lever operatir ely connected withthe cutting blade to effect adjustment thereof, and means for securingthe operating lever in the. required adjusted position.

4. In an implement of the character s ecified, a supporting frame, acutting b ade, front and rear "suspending chains for the cutting blade,draft sustaining chains, a longitudinally slotted bar supported by themain frame and having teeth along the length of the slot, an operatinglever connected with the cutting blade to effect ad- Ill) tions of thecutting blade, an operating lejustment thereof and adjustable in thelongitudinal slotof said bar, and means associated with, the lever andcoacting with the teeth of the bar to hold the lever and cutting bladein adjusted position.

5. In an implement of the character specified, a supporting frameincluding a longit'udinally slotted arched bar having teeth at on sideof the slot, a cutting blade, a bail having connection with opposite endporlever extending from said bailand passing through the slots of thearched bar, means associated with the lever and coacting with Wil saidteeth of the arched bar to hold the cutting blade in required adjusted.position, a separating device in the rear of the cutting blade andhaving loose connection therewith a crank shaft, and connecting meansbetween the crankshaft and separating device for imparting vibratorymovement thereto.

'7. In an implement of the character speci tied, a supporting frame, arear axle having ground wheels rotatable therewith, sprocket wheelsloose upon the axle and having c ut hed engagement therewith, crankshafts connected with the respective sprocket wheels, adjustable cuttingblades, separating devices having loose connection with the respectivecutting blades, and connecting means between the crank shaft andseparating devices for imparting vibratory movement thereto.

In testimony whereof I aflix my! signature in presence of two witnesses.

HENRY A. JOHNSON.
